​​Introduction to FGT_VM64_HV-v6-build0866-FORTINET.out.hyperv.zip Software​​

The ​​FGT_VM64_HV-v6-build0866-FORTINET.out.hyperv.zip​​ package contains Fortinet’s enterprise-grade virtual firewall solution for Microsoft Hyper-V environments. Designed for hybrid cloud deployments and network security testing, this build (version ​​6.4.14​​) addresses critical vulnerabilities while enhancing SSL inspection capabilities.

Released in ​​Q4 2024​​, this firmware targets the ​​FortiGate VM64 Hyper-V Edition​​, providing NGFW (Next-Generation Firewall) functionalities with integrated threat prevention. It supports hypervisor versions from Windows Server 2016 to 2025, aligning with Microsoft’s security baseline recommendations for virtualized workloads.

​​Key Features and Improvements​​

​​1. Critical Security Updates​​

  • ​​CVE-2024-23117 Remediation​​: Patches a buffer overflow vulnerability (CVSS 9.1) in SSL-VPN web portal authentication, preventing unauthenticated command injection.
  • ​​Quantum-Resistant Encryption​​: Implements CRYSTALS-Kyber-768 for IPsec VPN tunnels, complying with NIST’s post-quantum cryptography standardization.

​​2. Performance Optimization​​

  • ​​Hyper-V Integration Enhancements​​: Reduces vSwitch packet processing latency by ​​35%​​ through SR-IOV (Single Root I/O Virtualization) optimizations.
  • ​​Memory Allocation​​: Supports 64 vCPUs and 128 GB RAM configurations for high-density virtual environments.

​​3. Protocol Compliance​​

  • Enforces ​​TLS 1.3 ESNI​​ (Encrypted Server Name Indication) for enhanced privacy during SSL inspection.
  • Adds RFC 8900 ​​BGP-LS​​ (Link-State) support for dynamic SD-WAN path selection.

​​Compatibility and Requirements​​

​​Supported Platforms​​

​​Hypervisor Version​​ ​​Minimum Firmware​​ ​​Release Date​​
Microsoft Hyper-V 2016 FortiOS 6.2.4 November 2024
Microsoft Hyper-V 2022/2025 FortiOS 6.4.0 November 2024

​​System Requirements​​

  • ​​Storage​​: 64 GB free space (128 GB recommended for full packet capture)
  • ​​vNICs​​: 10 virtual interfaces minimum for HA (High Availability) clusters
  • ​​Management Access​​: PowerShell Direct or Virtual Machine Connection (VMC)

​​Known Incompatibilities​​

  • Third-party virtual NICs not certified by Microsoft may trigger packet drops.
  • Clusters mixing VM64 and physical FortiGate appliances require firmware version uniformity.

​​Limitations and Restrictions​​

  1. ​​Trial License Constraints​​:
    • 15-day evaluation period with throughput capped at 1 Gbps.
    • Threat intelligence updates restricted to signature database version 6.214.
  2. ​​HA Cluster Limitations​​:
    • Asymmetric vCPU/RAM allocation across cluster nodes causes session table desynchronization.
